Medical Xpress / New study finds a missing link in how the brain regulates appetite
When the stomach is full, how does the brain know to stop eating? Scientists long assumed the answer lies mainly with neurons, the brain's primary signaling cells. But a new study published in the Proceedings of the National ...
Medical Xpress / Molecular map could unlock new treatments for heart and lung diseases
Scientists have created a new "molecular map" uncovering how an important human receptor involved in blood clotting and inflammation works—an advance that could help us design better drugs for conditions such as pulmonary ...
Phys.org / Parasitic tapeworm—a risk to domestic dogs and humans—found in Washington coyotes
New evidence suggests that a disease-causing tapeworm that has been spreading across the United States and Canada has arrived in the Pacific Northwest. The tapeworm, called Echinococcus multilocularis, lives as a parasite ...
Medical Xpress / Treating tumors independently of oxygen: Photodynamic therapy uses hydrogen peroxide instead
Photodynamic treatment of cancer is based on administering an initially inactive substance that is only activated in the tumor via targeted light irradiation. It then generates reactive oxygen species that kill the cancer ...
Phys.org / Teachers tend to help the same kids repeatedly when using AI-powered tutoring tools
A new study finds teachers tend to provide assistance to similar subsets of students when using AI-powered educational tools, rather than touching base regularly with everyone in their classes. The findings could be used ...
Tech Xplore / Latest Anthropic AI model finds cracks in software defenses
Anthropic on Tuesday said its yet-to-be-released artificial intelligence model called Claude Mythos has proven keenly adept at exposing software weaknesses.
Medical Xpress / Study of 633,000 people links loneliness to suicidal thoughts
Loneliness plays an important role in the development of suicidal ideation, thoughts of ending one's life, which precedes nearly every suicidal death, according to a study by researchers at Vanderbilt Health. Their findings, ...
Phys.org / Astronomers thought the early universe was full of hydrogen: Now they've found it
The Eberly Telescope Dark Energy Experiment (HETDEX) has discovered tens of thousands of gigantic hydrogen gas halos, called "Lyman-alpha nebulae," surrounding galaxies 10 billion to 12 billion years ago. Known as Cosmic ...
Phys.org / Bird flu spread could be impacted by where waterfowl like to live
The movement patterns of waterfowl, including ducks, swans and geese, may affect the spread of highly pathogenic avian influenza in bird populations, according to a new study from the University of Georgia. The findings are ...
Phys.org / Rich biodiversity found in Japan's deepest ocean trenches, including an unidentified 'mystery' species
A new study published in the Biodiversity Data Journal provides a profound look at life up to nearly 10 kilometers below the ocean's surface in the Japan, Ryukyu, and Izu-Ogasawara trenches. The research catalogs at least ...
Phys.org / Ranks of Disparity: New approach fixes flaw in fairness algorithms
As organizations increasingly rely on algorithms to rank candidates for jobs, university spots, and financial services, a new method, named hyperFA*IR, offers a more principled approach when picking candidates based on a ...
Phys.org / Social honey bees stay cool: How groups mitigate heat-triggered hormone spikes
Heat can change a honey bee's hormone levels, but only if the bee is alone. New research from MSU entomologist Zachary Huang shows that isolated honey bees experience a rapid hormonal rise when exposed to high temperatures, ...
